Auxerre, the surprise leader of France's Ligue 1, had its seven-game winning streak come to an end when it fell to Paris St. Germain, 1-0, at Parc des Princes on Saturday. Seconds after Jeremy Clement put PSG ahead, AJA players thought they had a penalty when Roy Contout was brought down by PSG defender Mamadou Sakho, but the referee ruled foul took place outside the box. "This leaves a bitter taste because it was definitely a penalty," Auxerre coach Jean Fernandez said. "It's really a pity to see our strong run end this way." The win was bittersweet for PSG, which lost veteran goalie Gregory Coupet with a suspected broken leg.
